Application filed January To all whom 2'25 may concern:

Be it known that I, GEORGE GARLETON Gnnow, a British subject, residing at the city of Ottawa, in the county of Carleton and Province of Ontario, Dominion of Canadm'have invented certain new and useful Improvements in Oil Burners; and I hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to an oil burner so constructed that the heat radiated from the combustion bowl is utilized to bring the carburetted air before combustion to substantially the same temperature as that in the combustion zone, thereby obtaining optimum efiiciency as regards the complete combustion of the fuel and the thermal units given oii.

To this end I have provided the bowl with an enclosing jacket which forms with the bowl an annular chamber; this chamber hav ing air and oil inlets, juxtapositioned but separated by a baffle or partition that extends from the jacket to the bowl so that the air entering the chamber is compelled to circulate from the air inlet completely around the bowl to that part of the annular chamber in the vicinity of the oil inlet, where it is carburetted by the oil entering and passing through the annular chamber from the oil inlet to the combustion zone.

For the admission of the oil and carburetted air to the combustion zone, the bowl is provided with an inlet, in line with the oil inlet of the annular chamber, so that the oil thus will pass in a straight line across the annular chamber and create a suction through the annular chamber that maintains forced or rapid circulation of air into and through the annular chamber and around the bowl to the locus or that part of the annular chamber in the vicinity of the oil inlet.

For an understanding of the invention reference is to be had to the following description and to the accompanying drawings, in which:

The burner comprises a combustion bowl a, a jacket 2) surrounding the combustion bowl and forming with it an annular chamber Z), and a baflie e that extends from the combustion bowl a to the jacket 6.. The annular chamber at one side of the battle 6 is provided with an air inlet 0 and at the other side of the baffle is provided with an oil inlet d.

Formed through the wall of the combustion bowl is an inlet f from the annular chamber 7) to the combustion zone or interior of the combustion bowl (4, and this inlet is in line with the oil inlet (Z so that the oil entering through the oil inlet (Z will pass uninterruptedly across the annular chamber Z) and through the'inlet 7 into the interior of the bowl 0; under the pressure of the oil. feed. As the oil passes across that part of the annular chamber between the ot 65 and toe ii H 7 to the combustion her, it carburets and sucks the heated air into the combustion zone of the bowl and this suction maintains a forced circulation of from the air inlet through the r is chamber 6 around the combustion bo l to the inlet f.

Dated at the said city of Ottawa, this 26th day of December, A. D. 1924.
